Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a security flaw found in the Tenda CH22 device, specifically in the function formCertLocalPrecreate within the /goform/CertLocalPrecreate file of the Parameter Handler component.
The issue arises when the argument 'standard' is manipulated, leading to a stack-based buffer overflow.
This flaw can be exploited remotely, and an exploit has already been publicly released, which means attackers can use it to compromise affected devices.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to severe security consequences because it allows remote attackers to cause a stack-based buffer overflow.
Such an overflow can enable attackers to execute arbitrary code, potentially gaining control over the affected device.
This can result in unauthorized access, data compromise, disruption of device functionality, or use of the device as a foothold for further attacks.
